The building and construction sector is one of the most impactful for the environment, contributing to high CO₂ emissions, waste generation, and raw material consumption. Design for Disassembly (DfD) emerges as a promising circular economy strategy to enable material reuse and extend the building lifecycle.

摘要

The building and construction sector is one of the most impactful for the environment, contributing to high CO₂ emissions, waste generation, and raw material consumption. Design for Disassembly (DfD) emerges as a promising circular economy strategy to enable material reuse and extend the building lifecycle. However, to the best of the author’s knowledge, its large scale implementation, especially in the residential sector, remains underex-plored. This study aims to assess the environmental and economic impacts of applying DfD principles to single-family houses, which constitute a pre-dominant segment of the European building stock. Using a research design integrating Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) methodologies, the study evaluates different technological scenarios ranging from traditional construction to varying levels of DfD integration. Currently, a representative building typology has been developed based on Europe-an data and modeled in a Building Information Modeling (BIM) environment, allowing detailed material quantification. The next steps will involve implementing the LCA and LCC analyses. Evidence from the literature suggests that while DfD enhances circularity and resource efficiency, its economic feasibility may remain a challenge due to high initial costs and market constraints. This research could contribute valuable data to inform sectoral policies and macroeconomic models supporting sustainable building strategies.
